How Do I Reproduce This Heart
I want to plot a heart shape wireframe as shown in the following image:
I have tried to make it by using this MATLAB program:
n=100 x=linspace y=linspace z=linspace =ndgrid F= .* -.*.*) + + .* + -1).^3) isosurfacelighting phongcaxisaxis equalcolormap view
But I didn’t get the desired shape of framework as shown in the figure.
I have identified the problem: to create a wireframe we usually use the command mesh. But this plotting facility only allow us to plot a function of two variables such as z=f. But my program makes use of three variables: F.
How can I solve the problem?
Here’s my best attempt at reproducing the entire figure:

A human heart lies at the center of the chest slightly down and leaned towards left of the chest. It is a circulatory organ and its main function is to pump and circulate blood throughout the body. A dead heart is a dead human. Human heart is divided into four chambers named as upper left and right atria, lower left and right ventricles. The heart fence is made up of three layers, the inner endocardium, middle myocardium and outer epicardium. These are bordered by a pouch called pericardium. The deepest level of the heart is called the endocardium, while the middle layer of the heart wall is the myocardium. A heart has four valves, all four heart valves lay along the same plane. The valves guarantee blood flow in one direction through the heart and avoid backflow. Moreover the heart is divided as right heart and left heart in scientific terms.

How To Draw A Heart In 3d
If you want to draw your hearts in 3D for something like a candy heart drawing or a box of chocolates, its pretty easy to do.
You start with the same basic shapes and guidelines. And draw out your heart just like you would for a 2 dimensional drawing.
There are a couple of techniques you can use to add depth to your heart drawings.
You can use one point perspective where youd draw a vanishing point on your paper that all your lines will converge to.
Or you can use parallel lines to add depth and draw it out freehand. Its up to you but I usually draw them freehand.
How To Draw A 3d Heart
Everyone and anyone can draw a heart. Its fun and simple, fast and easy. Drawing a heart is so easy, people want to take it to the next level. The best way to do that is to make it 3D. Sadly, making a 2D figure look 3D is harder than it looks. This a simple, fun, effective guide to help you draw a 3D heart with ease. Lets get started!
If you would like to watch how to draw a 3D heart, watch this:
To draw a 3D heart, youll need drawing paper, a pencil, an eraser, and a ruler.
First of all, draw your heart. You can do it with your naked eye, but I decided to get fancy and use a ruler for the perfect proportions on my heart. First, I drew a line vertically down the middle of the paper. Then I drew a horizontal line across the first line. Next, I drew a triangle as the base of the heart by drawing up towards the horizontal line from the bottom of the vertical line. Use a ruler to make the lines the same length . This is vital so that the lines are at the same angle. I choose a two-inch length, so both of my lines should be two inches from the bottom of the vertical line, to the horizontal line.
Now, put your ruler away and draw an oval/circle on either side of the vertical line. These ovals should just touch the vertical line and a corner of the triangle.
Then, go over your lines to make a full heart. Erase the extra lines.
What is left of the bottom line trace over along with the curve it connects to. Go over all the lines you kept, and then we can move on to the shading.

Putting The Figure Together:
To reproduce the entire figure I first generated the heart mesh using the heart function above, then added the other elements around it. I also used a few submissions from The MathWorks File Exchange:
Here’s the code for the function I_Heart_Math :
function I_Heart_Math % Initialize heart plot and adjust figure and axes settings: heart set offset = get-get offset = 35.*offset./norm set % Create the axes and labels, offsetting them in front of the % heart to give the appearance they are passing through it: arrowStarts = +repmat arrowEnds = +repmat arrow text text text % Create the equation text: text % Create the large-type text: hI = text hM = text % Create an anti-aliased version of the figure too : set set myaa set set set end
A very elegant solution is given by . I though I extend it by adding the other elements to replicate the figure pointed by the OP. I also added some cool animations!

Generating The Contoured Heart Mesh:
I used the contourc function to generate a series of contours in the x-y, x-z, and y-z planes. Notice that in the image you want to reproduce, the mesh lines on the back-facing side of the heart are not rendered. The quickest and easiest way I could think of to reproduce that aspect of the plot was to use isosurface to render a white surface just beneath the inside surface of the mesh, blocking the view of the back side.
Here’s the code for the function heart:
function heart % Initialize the volume data, figure, and axes: = meshgrid) F = -X.^2.*Z.^3-.*Y.^2.*Z.^3+.*Y.^2+Z.^2-1).^3 hFigure = figure hAxes = axes view % Create and plot contours in the y-z plane: for iX = plane = reshape,101,101) cData = contourc xData = iX.*ones) plot3,cData,'k') end % Create and plot contours in the x-z plane: for iY = plane = reshape,101,101) cData = contourc yData = iY.*ones) plot3,yData,cData,'k') end % Create and plot contours in the x-y plane: for iZ = plane = F cData = contourc startIndex = 1 if size > +1) startIndex = cData+2 zData = iZ.*ones) plot3),... cData),zData,'k') end zData = iZ.*ones) plot3:end),... cData:end),zData,'k') end % Fill the inside of the mesh with an isosurface to % block rendering of the back side of the heart: p = patch) set end
